The fifth warmest January on record – significant weather variations in the north and south
January 2026 marked the fifth warmest January on record globally, despite notable cold spells in Europe due to unusual polar jet stream activity.
January 2026 was officially recorded as the fifth warmest January globally, indicating continued concerns over climate change, though it was 0.28 degrees cooler than the previous year, which had been the warmest ever documented. The average global temperature for January was 12.95 degrees Celsius, surpassing historical averages and remaining within the thresholds set by the Paris Agreement for curbing climate change. Notably, while this trend reflects higher global temperatures, Europe experienced significant cold during the same month, with temperatures plummeting to an average of -2.34 degrees Celsius, marking the coldest January in the continent since 2010. This disparity highlights irregular weather patterns and extremes that continue to plague regions due to shifting climate dynamics. The drastic variations in weather, attributed to unusual fluctuations in polar jet streams, have disrupted normal climate patterns, pushing Arctic air downwards. Such developments not only affect weather forecasts and climate policies in Europe but also signal an urgent need for collective global action to mitigate climate impacts, given the potential social and economic ramifications of extreme weather events.
